11 Claims. (Cl."259-. 131) The present invention relates toimprovements.

beater blades to prevent their interference with the side walls of thevessel in which the beater is operated.

I have illustrated a preferred" embodiment of my invention in theaccompanying drawing, in

which a a Figure 1 isan' elevation of abeater embodying the improvementconstitutingthepresent invention, I 1

Figure 2 is a section on line 2 2 of Figure 1,

and ,7 Figure 3 is a of the beater frame. I r I 7 Referring now to thedrawing, reference numeral 10 designates a bifurcated frameterminatingdownwardly in two sockets 11 and 12 and having journaled ona transverseaxis therein a gear 13v adapted to be rotated by a crank 14. vtransverse handle 15 is secured to the upper end of frame 10 in theusualmanner,,andsoclrets l1 and 12 are joined by meansof a,yoke 16.; vSecured in sockets-1 1, and 12. are the upper ends of legs 1'7 and 18which provide upper and lower journal portions for beater blades 19 and20 to the upper ends of which are fastened gears 2land 22 meshing withgears 13 tobe driven:

thereby. 11 r a At their lower ends, legs 1'7. and 18 are provided withdivergently bowed portions 23 and 24, and immediately below these arethe lower journal portions already referred to, designated at 25 and 26.Legs 17 and 18 form the side members of what may be termed asubstantially U-shaped frame having a cross portion made up of sections2'7 and 28. As here shown, sections 27 and 28 at their adjacent ends arerectangularly bent in a plane perpendicular to the plane of legs 1'? and18 and extend side by side as at 29 and 30, an integral loop-like footsection 31 joining sections 29 and 30 and surrounding thelower journalportions 25 and 26, as here shown, in substantially symmetrical relationthereto. It will be understood that while sections 29 and 30 and forthe. beaters.

loop '31 are shown as being integral withlegs 17 and 18, thisconstruction is notabsolutelynecessary, although preferable. Further, inthebroad aspect of the invention, loop 31 need not be of the symmetricalform as shown but maybe shaped 69;

in any appropriate manner.

It will be noted from Figure 2 that loop 31 is somewhat elongated and atits ends is in the form of semi-circles developed on radii substanetially equal to the length, of sections 29 and-30 65. about journalportions 25 ,and 26' as centers.

-It will beunderstood that the present'invention relates only totheframeor frame portion 9 just describedand is not concerned with theupperframe 10 and its associated mechanism which maybe of any preferredform. The frame or frame,

portion of the, present invention-is ordinarily made of heavy wire toprovide a very; rigid struc'-- ture. Undersome circumstances, as when a;lighter frame wire is used so that-theinherent rigidity of the frame isimpaired, means, such as a drop'of solder, may be used to preventseparation of sections 27 and 28.

It will be understood that the described em bodiment of my inventionismerely illustrative and that I do not limit myself except asdetermined in the following claims. 7

What I claim is: I I 195 1.
